7. ### A car traveling 25 m/ s to applies to the brakes to decelerate at 5.5 m/ s ^2. How long does it take the car to come to a complete stop?​?

Initial velocity, u = 25 m/ s Final velocity, v = 0 m/ s Acceleration, a = -5.5 m/s² v = u + at 0 = 25 + (-5.5)t Time taken, t = 25/5.5 = 4.5 s

8. ### A car accelerates uniformly in a straight line from rest at the rate of 2.8 m/ s ^2. What is the speed of the car after it has traveled 54 m?

v² = u² + 2as so, v² = 0² + 2(2.8)(54) Hence, v² = 302.4 => v = 17.4 m/ s       v = u + at so, 17.4 = 0 + 2.8t => t = 6.2 seconds :)>
